T0 all whom it may concern:

Be it known that I, NATHAN M. STANLEY, a citizen of the United States, residing at in the county of Montgomery and State of Ohio, have invented certain new and use-ful Improvements in Processes for Making Composite `hletallic and Non- Metallic Stock, of which the following 1s a specification, reference being had therein to the accompanying drawing.

This invention relates to a. process for making composite metallic and non-metallic stock, preferably in or ribbon, and embossing and severing sections of said stock to constitute a productin the nature of labels for application to articles of commerce. y y

The object of the invention is to produce, more expeditiously, and in a` cheapened manner such labels, and to emboss thereon letters, figures, designs, and decorations of various kinds, applicable to a variety of articles as candy boxes, hats, music cases, for marking, illuminating or decorating the same, or for other useful purposes.

The present invention relates to improvements upon the process set forth in my former Patents No. 1,018,138, issued February 20th, 1912, and No. 961,550, issued June 14th, 1910. l

Fig. 4 is a plan view of thejdry- Under my Letters Patent No. 1,018,138 the process consisted in winding spirally upon a reel the metal ribbon, and dipping the reel by hand into an alkaline bath to remove the grease, etc., from the metal; removing the reel from the alkali and immersing it by hand in a receptacle of Water to cleanse it;.then dipping the reel in receptacles containing acid and water respectively, to give the metal a mat-surface and to cleanse it of acid and the soluble precipitates. After this the reel was placed in a receptacle or crock containing suitable drying material, as sawdust, and was moved about therein so that the surface of the metal was thoroughly dryed.

Under my Letters Patent No. 961,550, the process was to move the metal through an acid bath and then pass it through an alkaline bath to neutralize the effect of the acid on the metal. I then unwound the metal over a heated drum and applied an adhesive directly to the metal; the adhesive was contained in a receptacle surrounded by a water chamber to provide a means of keeping the adhesive at a proper consistency for application to the metal sur'- face. l then wound the metal upon a drum so that the adhesive could dry. After this, l subjected the ribbon to a die and punch, and the resultant letter or figure was, by pressure, forced into the surface to which it was to be attached so that the letter would lie flush with the surface of the material supporting it and become firmly embedded therein.

When the metallic strip enters my present process itv cornes as clean stock and passes 'from a suitable 'reel into a bath of acid to give it a' mat-surface, and while in the vertical zinc plates, placed one at the entrance of the ribbon to the' acid bath and one at the exit from the acid in such a position as to keep the ribbon in the bath, flex it slightly to permit the acid to react fully, yet not to so bend it as to spread, warp, twist, or pull the ribbon, which has been a serious difficulty when frequently flexed or reeled. The inherent difficulty of rolls moving in an acid bath is thus obviated.

The ribbon passes directly in unbroken movement, under a water spray, through water baths, being threaded under and over I small revolving brushes provided with movement ofthe ribbon, so that metallic sulfates resultant from the chemical action absorbent material of acid on metal 4are thoroughly removed; thence, directly in uninterrupted progress, the ribbon passes into a receptacle containing an abrasive, absorbent drying material, as for instance sawdust, where the ribbon is threaded between revolving brushes having flanges at each end to'prevent a lateral movement of the ribbon, s o that all portions of the ribbon are dried, cleansed, and 4polished during its passage throughout the length of the drying receptacle. I now have a mat-like surface thoroughly cleansed, dried, and polished, having been iexed only to a minimum extent, and reeled but once,

. and at no time having been touched by hand.

In the passage from bath to bath, the ribbon is protected from injury by the sharp edges of the receptacle by means of a pad of soft placed on such edge, as soft leather. Y

Referring to Fig. 1, 1 designates the reel of metal2 is the metal ribbon as unwound from the reel passing directly through the apertures 4, in frame 5, placed in the acid 6, contained in receptacle 3. The container or receptacle is drained by the waycock 7. The ribbon passes over pads 8, under a water spray 9, and into a water bath 10 in and between brushes 12, 12, in a container 11, drained by a cock 13. The ribbon then passes over pads 8, and over and under brushes 12, 12, in a second water bath 14, in

a container l5 drained by a cock 16. Thence,

the ribbon is conducted over the-'pads 8, 8, under and over brushes 17, 17, through drying material 18 in a container 19, and reeled on a reel 20. I next apply to one surface of the strip a lacquer, and then bake the lacquered stri in order to prevent any tarnishing of the step, I pass the ribbon through an oven, wherein the lacquered metal-is baked at a suitable temperature frthe requisite time.

The ribbon is strung or draped the length of Ithe oven over spools, at no time abruptly reeled or strained unduly. During its passage through the oven at a pre-determined-A speed, it thus remains apre-determined time therein, acquiring a uniform luster. The ribbon.. is now in reeled form.

Referring to Fig. 2, 21 designates an air compressor furnishing air to the lacquer tank 22, from which lacquer is forced through tube 23 and spreader 24, onto the oven over a. guiding roll or sheave 29, and is i metal ribbon 2 passing thereunder. The ribbon 2 passes thence over a guiding roll 25 into a baking oven 26, where it is draped over rolls 27, 27 placed at opposite ends of the oven and turning on shafts 28, 28. When baked, the lacquered ribbon passes out of the ished product, and to secure great durability and beauty. In this baking "brush 4which engages and of the ribbon having the coat of adhesive,

reeled at 30. The heat supply pipe for oven that there is secured a perfect spread of the his non-metallic mai terial 1s moistened by a slzmg substance so subsequent coat of adhesive at all parts of the ribbon. In order to secure a very per-y fect product, this composite metallic and non-metallic ribbon is passed over a pad and another coat of glue ap lied to the face of the non-metallic side ofp the com osite ribbon. This step in the process is oth more eiectiveA and practical, and considerably faster 'than the old method, as at no time is the ribbon reeled on a small roll while being handled, and the treatment of it by hand is reduced to a minimum.

Referring to Fig. 3, 33 indicates the reel of paper ribbon 35 passing under a moistener consisting of a cup 32 containing the sizing, a roll 34, and a pad 37; the paper ribb'on passes over the revolving sheave 36 and thence directly beneath the roll 38 where it is joined with the glued surface of the metal and 2 are joined.' The conjoined stock passes as the ribbon 42, under glue cup 43 where a coating of adhesive is applied to the non-metallic side of the ribbon; the adhesive is applied evenly by spreader 44. I then pass the ribbon on to a long revolving roll or reel of large diameter composed of a series of sections. As the ribbon passes von to the reel, there is a suitable revolving rubs the surface causing the metallic and the non-metallic ribbons to adhere closely to each other.-

This is particularly valuable when the air is very dry. As the ribbon is exposed in its progress over the reel to varied currents of air, it is not stretched, warped, or twisted unduly, for by virtue of the large diameter of the reel, the ribbon can be spirally wound at a low pitch, thus causing a minimum amount of transverse strain upon the ribbon. If this strain were large in amount the non-metallic ribbon might buckle on the metallic ribbon. From the large reel I pass the ribbon to a small reel.

Referring to Fig. 4, the composite stock passes under brush 45, and then is spirally wound on reel 46 revolving on shaft 47. This reel 46 has the ribbon 42, of composite 'the shaft 47. Rims lib ,moving the sections 49,

` marion material, wound upon it-spirally, at a low itch. Immediately before lpassing to the reel 46, the ribbon 42 engages the brush 45. When the ribbon 42 has revolved the course of the reel, it passes to a small reel 48 where it is concentrically wound.Y The reel is revolved by a band 77 from power ulley 78.

Fig. 5 indicates an end View oi? the reel 46. This section of the reel, as well as the other sections of the entire reel, is divided in halves 58 and 59, hinged at 53 and latched at 54 on shaft 47. Bearings 55 embrace 56, support cleats 57 arranged about the periphery of the reel, parallel to its longitudinal axis.

Fig. 6 is a perspective of the shaft 47, in a part of whose length runs a spiral groove 60. A spring plunger 61, carried in the bearing55, the shaft, travels in the spiral groove 60, 50, etc., of the reel forward4 toward bearing 62 rogressively 63, which bearings support om i bearingv shaft 47.

"Referring, to Fig. 7, in, the bearing is v`shoirvn a 'plunger 6l., 79 ..being a .spring portions,

heldingthe plunger inengagement with the shaft 47, while traveling in the groove 60, the plunger andspring being carried in bearing 55,.

The composite stock -asses from the small reel at a determina le rate under an embossing die or other die, and a cutting die, to remove the desi and a suitable area about it from the ri bon. These several now constituting labels or individual letters, characters, etc., as the case may be, are automatically counted, until a suitable number have accumulated. They are then dropped through a guide chute into a box in which they can be finally acked, as desired. This box is one of a series, automatically transported on an endless chain carrier traveling at a pre-determined rate, the empty boxes being suitably brought into position at a moment when the labels are released.

Referring to Fig. 8, 48 is the reel of composite stock passing as a ribbon 4 2, between the guiding rolls 64, 64, under an embossing die 65, and a punch 66 which severs from the now embossed stock 67 the design and suitable adjacent -area 68, from the ribbon. The severed portions fall into a chute 69, and thence into box 70 or the like, carried on endless chain 71, propelled by sprocket wheel 72.

In Fig. 9 is illustrated, in addition to the embossing and stamping apparatus, a conventional counting mechanism comprising an adjustable arm 7 3 which actuates 'a pawl 74 that operates a ratchet 75 operating a cut-od 77, through a pitman 76. Motion is delivered to this mechanism through pulley 7 8'. i

at right angles to the axis of" `wish to limit myself Eig. 10 is the 'composite ribbon 67 with designs 68 embossed thereon. Fig. 11 is the l completed product, with design 68 and suitable adjacent area constituting the label.

I may, also, lacquer the finished product in order to doubly insure the face ofthe label from tarnishing. This may be performed by moving the labels when finished, in the above manner, on an endless chain conveyer under a lacquer spray and allowing the product to dry in the air currents. Thus the product will have a perfect coat of lacquer whether the original lacquer was disturbed by the embossing and punching or not.

It ma be remarked that to avoid injury to the ne metal ribbon, it is particularly desirable to flex, wind, bend, or handle 1t as little as possible. `The minimum of this is attained 1n my improved process; speed and economy of time and space, are also effected to a greater degree by this process than has been heretofore posslble in the art.

lit will be apparent that the details described may be varied more or less without ,departing from the essential steps in carry- T, therefore, do not to those unessentials. The embossing and severing can, of course, be limited to embossing and severing individual or separate letters or characters, as distinguished from embossing a group of letters or characters and severing a section of the stock containing such group, but the latter is the preferred product of the process.
